4 1.0 Introduction Nuvair has taken extreme care in providing you with the information you will need to operate this system. However, it is up to you to carefully read this manual and make the appropriate decisions about system safety. This manual will assist you in the proper set-up, operation and maintenance of the Nuvair Voyager III TM Nitrox System. Be sure to read the entire manual. Throughout this manual we will use certain words to call your attention to conditions, practices or techniques that may directly affect your safety. Pay particular attention to information introduced by the following signal words: Indicates an imminently hazardous situation, which if not avoided, will result in serious personal injury or death. Indicates a potentially hazardous situation, which if not avoided, could result in serious personal injury or death. Indicates a potentially hazardous situation, which if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. Notifies people of installation, operation or maintenance information which is important but not hazard-related. Page 4

5 2.0 Safety Warnings This equipment is used to provide breathing gas for the purpose of underwater life support. Read this manual in its entirety. Failure to heed the warnings and cautions contained in this document may result in severe injury or death. The equipment you will be using to manufacture Nitrox (oxygen rich air) will expose you to both low and high-pressure gas. Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to be directed at any part of your body. Any pressurized hose can cause extreme harm if it comes loose or separates from its restraint (or termination) while under pressure and strikes any part of your body. Use appropriate care in making and handling all gas connections. Pure nitrogen is a colorless, odorless, tasteless gas that will not support life. Breathing gas mixtures containing more than 84% nitrogen at surface pressures will lead to unconsciousness and may cause death. The nitrogen discharge from the Membrane System must be vented to the exterior of any closed building, boat, or similar enclosed space. Breathing gas mixtures containing more than 84% nitrogen at surface pressure will lead to unconsciousness and may cause death. Do not use any form of mineral oil or synthetic lubricant not rated for Nitrox in any Compressor in this system. Use only the recommended Nitrox Compressor Lubricant. Never mix the Nitrox Compressor Lubricant with other lubricants. Remove all existing lubricant and replace with the proper Nitrox Compressor Lubricant prior to installing the Membrane System. The use of improper lubricants can lead to fire or explosions, which may cause serious personal injury or death. Do not use this system to produce Nitrox mixtures containing more than 40% oxygen. Pumping Nitrox mixtures with higher concentrations of oxygen may lead to fires or explosions, which can cause serious personal injury or death. Page 5

6 The use of enriched air Nitrox does not eliminate the risk of decompression sickness (DCS) in diving. Decompression sickness can lead to permanent disability or death. Do not pump Nitrox mixtures at pressures above the HP Compressor manufacturer s rating, and never above 3600 P.S.I. (250 bar). The system is not rated for pressures above 3600 P.S.I. (250 bar). Higher pressures may lead to explosions which may cause serious personal injury or death. Ambient room temperature should never exceed 100 o F (38 o C) during operation of the Nitrox System. Operation at higher temperatures may lead to system damage and malfunction. A damaged membrane will not produce the correct Nitrox mixture which can lead to severe personal injury if the gas is used for diving purposes without proper analysis. Page 6

7 3.0 Safety And Operation Precautions Because a compressor is a piece of machinery with moving and rotating parts, the same precautions should be observed as with any piece of machinery of this type where carelessness in operations or maintenance is hazardous to personnel. In addition to the many obvious safety precautions, those listed below must also be observed: 1) Read all instructions completely before operating any compressor or Nitrox System. 2) For installation, follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Administration (OSHA) standards. 3) Electric motors must be securely and adequately grounded. This can be accomplished by wiring with a grounded, metal-clad raceway system to the compressor starter; by using a separate ground wire connected to the bare metal of the motor frame; or other suitable means. 4) Protect all power cables from coming in contact with sharp objects. Do not kink power cables and never allow the cables to come in contact with oil, grease, hot surfaces, or chemicals. 5) Make certain that power source conforms to the requirements of your equipment. 6) Pull main electrical disconnect switch and disconnect any separate control lines, if used, before attempting to work or perform maintenance. Tag Out or Lock Out all power sources. 7) Do not attempt to remove any parts without first relieving the entire system of pressure. 8) Do not attempt to service any part while System is in an operational mode. 9) Do not operate the System at pressures in excess of its rating. 10) Do not operate compressor at speeds in excess of its rating. 11) Periodically check all safety devices for proper operation. Do not change pressure setting or restrict operation in any way. 12) Be sure no tools, rags or loose parts are left on the Nitrox System. 13) Do not use flammable solvents for cleaning the Air Inlet Filters or elements and other parts. 14) Exercise cleanliness during maintenance and when making repairs. Keep dirt away from parts by covering parts and exposed openings with clean cloth or Kraft paper. 15) Do not operate the compressor without guards, shields, and screens in place. 16) Do not install a shut-off valve in the compressor discharge line, unless a pressure relief valve, of proper design and size, is installed in the line between the compressor unit and shut-off valve. 17) Do not operate in areas where there is a possibility of inhaling carbon monoxide, carbon dioxide, nitrogen, or flammable or toxic fumes. 18) Be careful when touching the exterior of a recently run electric, gasoline, or diesel motor - it may be hot enough to be painful or cause injury. With modern motors this condition is normal if operated at rated load - modern motors are built to operate at higher temperatures. 19) Inspect unit daily to observe and correct any unsafe operating conditions found. 20) Do not play around with compressed air, nor direct air stream at body, because this can cause injuries. 21) Compressed air from this machine absolutely must not be used for food processing or breathing air without adequate downstream filters, purifiers and controls and periodic air quality testing. 22) Always use an air pressure-regulating device at the point of use, and do not use air pressure greater than marked maximum pressure. 23) Check hoses for weak or worn conditions before each use and make certain that all connections are secure. The user of any compressor or Nitrox System manufactured by Nuvair is hereby warned that failure to follow the preceding Safety and Operation Precautions can result in injuries or equipment damage. However, Nuvair does not state as fact or does not mean to imply that the preceding list of Safety and Operation Precautions is all-inclusive, and further that the observance of this list will prevent all injuries or equipment damage.

8 4.0 Legal Precautions It is highly recommended that a Nitrox fill log be maintained when filling Scuba cylinders to document the following information. This log must be of permanent binding style with no loose pages. Fill date and time of day Tank Number Supplier s check of oxygen content (%O 2 ) plus signature and date User s check of oxygen content (%O 2 ) plus signature and date Fill Pressure MOD (Maximum Operating Depth) in user s handwriting Nitrox certifying agency and card number Page 8

9 5.0 Theory of Operation Voyager III TM Nitrox System The Voyager III TM Nitrox System is a turnkey package that produces oxygen-rich air (Nitrox) and then compresses it with a High Pressure (HP) Compressor to fill Scuba Tanks or storage cylinders. The package is designed to be fully automatic, with a quieted enclosure for noise reduction and protection from moving parts while it is running. Although it is described as the Nitrox Compressor, it can also be used to pump air. The Nitrox System allows for efficient and cost effective Nitrox production using electric power, without the hazards or expense of blending with stored high-pressure oxygen (O 2 ). Instead, the system uses a Semi-Permeable Membrane to produce Nitrox from air. A portion of the nitrogen in air is separated out, leaving an oxygen rich Nitrox mixture. The Voyager III TM uses a Rotary Screw LP Compressor, Air/Oil Aftercooler, Refrigerated Air Dryer, and Filtration to provide the Membrane System with a source of clean, pressurized feed air for separation. The air is filtered to CGA Grade D or better air quality prior to entering the Membrane System so it will not damage or plug the Membrane fibers. Specifications for Grade D air are provided in the Appendix. The Voyager III TM s Membrane System is rated for a maximum feed air pressure of 300 P.S.I. (21 bar) and has been configured to work well with the 175 P.S.I (12 bar) maximum pressure delivered by the LP Compressor. A Back Pressure Regulator is used to adjust the amount of air the screw compressor produces to meet the appropriate levels for various %O 2 Nitrox production. The air is then heated to a temperature that provides stability over a wide range of ambient conditions, is optimal for Membrane permeation, and prevents moisture condensation. The heated air enters the Membrane, which is made up of thousands of miniature hollow fibers. The walls of these fibers are semi-permeable and designed for different gases to move through them (or permeate) at different speeds. The resulting gas mixture is known as the permeate. As air flows through the hollow fibers, both oxygen and nitrogen permeate through the fiber walls. The oxygen permeates faster than the nitrogen, which produces permeate with oxygen content greater than air. The gas that reaches the end of the hollow fibers without permeating is almost entirely nitrogen and is discharged. The flow rate of this discharge is set by the factory via a fixed orifice, which controls the permeate to contain a constant 44% O 2 under normal operating conditions. The permeate is a concentrated mixture that must be diluted with additional air prior to entering the HP Compressor. It exits the Membrane at ambient to slightly negative pressure and travels into the Mixing Tube, where it mixes homogeneously with filtered outside air. The amount of dilution, and thus final %O 2, is obtained by adjusting the amount of air produced by the compressor and supplied to the membrane, with the Back Pressure Regulator. As air flow to the membrane is increased, permeate flow increases and a higher %O 2 Nitrox is produced. As air intake flow to the membrane is decreased, permeate flow decreases, compressor intake air increases, and a lower %O 2 Nitrox is produced. This relationship between permeate flow and intake air flow exists because the total of these two flow rates will always equal the intake flow rate demanded by the HP Compressor. The resulting Nitrox mixture is analyzed for %O 2 before entering the HP Compressor for approximate content and again when pumping Nitrox for precise content. The HP Compressor pumps the Nitrox to a maximum pressure of 3600 psi (250 bar) to fill Scuba Tanks or storage cylinders. A unique feature of Nuvair Nitrox Systems is that the feed air pressure that correlates to a specific Nitrox %O 2 is repeatable. For example, if your HP Compressor pumps 36% O 2 when the feed air pressure is at 125 P.S.I. (9 bar), then adjusting the Back Pressure Regulator to 125 P.S.I. (9 bar) during the next use will produce the same mixture. Page 9

18 13.0 Installing the Voyager III Nitrox System If any information in this manual conflicts with any of the other manuals call Nuvair before proceeding. Ambient room temperature should never exceed 100 o F (38 o C) during operation of the Nitrox System. Operation at higher temperatures may lead to system damage and malfunction. A damaged membrane will not produce the correct Nitrox mixture which can lead to severe personal injury if the gas is used for diving purposes without proper analysis Precautions 1. Please read all information supplied before physically installing the Nitrox System. 2. Unpack the system and remove from the pallet. Visually inspect the system to make sure there has been no damage during shipping. If damaged, please call Nuvair to file a damage report. Please take photos and supply detailed information about the damage. 3. Place the system in a location that allows a minimum spacing of 18 from adjacent walls. Select a location where ambient room temperature will never exceed 100 o F (38 o C). 4. The Heater Thermostat has been set in the factory. Do not adjust Nitrogen Discharge Hose The nitrogen discharge from the Membrane on the Voyager III exits next to the exhaust air fan. The fan pushes over 3000 cfm of exhaust air and as long as the fan is functioning there will be no need for an outside optional discharge, unless installed in a properly ventilated room. Pure nitrogen is a colorless, odorless, tasteless gas that will not support life. Breathing gas mixtures containing more than 84% nitrogen at surface pressures will lead to unconsciousness and may cause death. The nitrogen discharge from the Membrane should be vented to a well-ventilated room or to open air with good circulation. Failure to isolate the discharge from the air intake of the Membrane System or LP Compressor could lead to incorrect Nitrox mixtures, resulting in serious personal injury or death. If you allow this pure nitrogen to accumulate in an enclosed space, anyone entering this space will quickly lose consciousness and will die if not immediately resuscitated. Page 18

19 13.3 Electrical Power Connection Never use extension cords to provide power to your Nitrox System. The system must be properly wired according to national and local electrical codes by a qualified electrician. Improper wiring may lead to fires, which can cause serious personal injury or death. Prior to making the electrical power connection, check all system specifications provided in this manual. When working on the Nitrox System the main breaker at the power source must be locked out in the Off position. The Nitrox System has electrical protection for the Compressor Motor and Membrane System Heater located inside the motor starter compartment. Amperage Load for System Approximately 68 A for 230 V three phase service Approximately 34 A for 440 V three phase service HP Hour Meter LP Hour Meter Compressor Rotation Check HP On/Off Switch LP On/Off Switch Always turn on (bump) starter for both LP and HP Compressors and run motor very briefly to check for proper direction of rotation (see arrow on belt guard and flywheel). HP Compressor Shown Note Proper Direction of Rotation Operation in reverse direction for extended periods of time will cause a Reciprocating Compressor to run hot and perform poorly and may cause permanent damage. Reverse rotation for a rotary screw compressor for even a short period of time will cause damage. Page 19

20 13.4 Check Compressor Lubricant Levels Check lubricant levels before starting the LP and HP Compressors, and add lubricant as required. Use only the lubricants specified. LP Oil Fill & Dip Stick Compressor Lubricant Level Sight Gauges Do not allow Nitrox to be discharged into the air storage system. Nitrox introduced into the air storage system could cause a diver to suffer from oxygen poisoning at depth. Oxygen poisoning is extremely dangerous and can lead to drowning. Do not allow air to be discharged into the Nitrox storage system. Air introduced into the Nitrox storage system could cause a diver to suffer decompression sickness if the Nitrox mixture is not analyzed properly and is used underwater under the assumption it is a different mix Control Panel Controls HP Compressor Oil Pressure Gauge O2 Analyzers LP Feed Air Regulator Adjustment Knob Feed Air Pressure Gauge Cabinet Temperature Gauge Stage Pressure Gauges Fill Pressure Gauge On/Off Switches Heater Temperature Gauge LP Compressor Oil Temperature Page 20

21 14 Pre-Operation of Compressor Before Producing Nitrox 14.1 Calibrate Oxygen Analyzers Gas production is monitored with the Permeate Oxygen Analyzer before entering the HP Compressor to obtain a rough estimate of %O 2 (+/- 2%); however, do not rely on this reading as an indication of %O 2 at the HP Compressor outlet. Prior to pumping Nitrox from the Compressor, it must be monitored with the Fill Oxygen Analyzer to obtain a precise measurement of %O 2 (+/- 1%). Both Oxygen Analyzers must be calibrated prior to each use. Oxygen Analyzers must be calibrated before each use. See Oxygen Analyzer manuals for correct calibration procedures. Improper calibration of the Fill Oxygen Analyzer may result in the use of incorrect Nitrox mixtures, which may cause serious injury or death to the diver using the gas mixture. At altitudes above sea level, a correction factor must be used when calibrating the Fill Oxygen Analyzer may not be achievable. See Fill Oxygen Analyzer manual for correcting analyzer readings at various altitudes. Improper calibration of the Fill Oxygen Analyzer may result in the use of incorrect Nitrox mixtures, which may cause serious injury or death to the diver using the gas mixture. The Permeate Oxygen Analyzer supplies oxygen readings that can vary +/- 2% O 2 due to heat, humidity, and pressure changes experienced in the Nitrox flow and therefore should only be used for rough estimates of %O 2. The Fill Oxygen Analyzer supplies more accurate oxygen readings, within +/- 1% O 2. For Scuba cylinder Nitrox fills, the user must always verify the final fill with a third independent Oxygen Analyzer. Page 21

22 Compressor Controls Voyager III TM Nitrox System On/Off Knob for HP Compressor Fill Oxygen Analyzer Provides Precise Reading Calibration Knob Permeate Oxygen Analyzer Provides Rough Reading 1) Turn on the High Pressure Compressor and allow to run for 1-2 minutes or until Analyzers stabilize. 2) Crack open the bleed valve on the side of the compressor so that the running HP Compressor maintains P.S.I. ( bar) outlet pressure. Air will now be flowing past both Oxygen Analyzers for calibration purposes. 3) Monitor all gauges for proper operating range and check all connections for leaks.(page 20) 4) Calibrate Oxygen Analyzers while the HP Compressor is pumping air. Refer to the Oxygen Analyzer manual included with the Nitrox System for details. Note that special calibration procedures may be required when operating at altitudes above sea level. Permeate Oxygen Analyzer Turn calibration knob so display reads 20.9%. a. Fill Oxygen Analyzer Remove the Flow Adapter Cap covering the Sensor. b. Expose the Sensor to ambient air for approximately 15 seconds. c. Adjust Calibration Knob until Display reading stabilizes at 20.9%. d. Reinstall the Flow Adapter Cap to the analyzer. e. The Fill Oxygen Analyzer is now ready for use. Different settings may be used depending on location, so verify your actual ambient conditions and refer to the Oxygen Analyzer manual for details. 5) Turn on the LP Compressor and increase the pressure to a minimum of 90 P.S.I. 6) Allow the Compressors to run for a 10 Minute warm up period for the Membranes to warm up and stabilize. Check the Heater Fill Oxygen Analyzer Sensor Cap Removed Calibration Knob Temperature Gauge to verify air temperature rises and is between ºF (40-49 ºC). 7) Turn off LP Compressor and Re-Calibrate The Fill Analyzer. 8) Now that the System Temperature has stabilized You must Re-Calibrate the Fill O 2 Sensors. See Step 4a above. The Oxygen Analyzers may require re-calibration after minutes of operation due to humidity and temperature change effects on the Sensor. To recalibrate, Turn off the LP Feed Air and follow calibration instructions. Page 22

23 15.0 Producing Nitrox Before using your Nitrox System to pump Nitrox, test a sample of the Nitrox produced using the Air/Nitrox Quality Analysis Kit provided to verify compliance with CGA standards. Quarterly testing is mandatory once the System is operational. The equipment you will be using to manufacture Nitrox (oxygen rich air) will expose you to both low and high-pressure gas. Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to be directed at any part of your body. Do not change the temperature setting on the Thermostat Control without contacting Nuvair. Changes in temperature settings may cause Membrane damage. A damaged membrane will not produce the correct Nitrox mixture which can lead to severe personal injury if the gas is used for diving purposes without proper analysis Flow to Membrane and Setting Proper Pressure The Membrane System feed air pressure determines the %O 2 of the Nitrox mixture. As pressure is increased, a higher %O 2 Nitrox is pumped. As pressure is decreased, a lower %O 2 is pumped. 1) Increase pressure by slowly turning the regulator Knob CW while monitoring the LP Pressure Gauge and Permeate Oxygen Analyzer. As the pressure rises, watch the corresponding increase in the analyzer %O 2 reading. 2) Increase or decrease pressure slowly until the Permeate Oxygen Analyzer displays the %O 2 desired in the final Nitrox mixture. Regulated Membrane System pressure range should be P.S.I ( bar), depending on Nitrox %O 2 being produced. Heater temperature range should be ºF (40-49 ºC) Final Adjustments Before Pumping Nitrox Permeate Oxygen Analyzer 1) As the Nitrox initially makes its way through the running HP Compressor, the %O 2 reading on the Fill Oxygen Analyzer will slowly increase to read approximately the same %O 2 as the Permeate Oxygen Analyzer. This should happen within 3-5 minutes. 2) When the two analyzers read within +/- 1%, make any final adjustments to the Membrane System feed air pressure necessary to obtain the exact Nitrox %O 2 desired as indicated on the Fill Oxygen Analyzer. 3) The system is now ready to pump Nitrox. 4) Now you re ready to close Bleed Valve and open Storage System. Fill Oxygen Analyzer Page 23

24 The use of enriched air Nitrox does not eliminate the risk of decompression sickness (DCS) in diving. Decompression sickness can lead to permanent disability or death.\ The Permeate O 2 Analyzer supplies oxygen readings that can vary +/- 2% O 2 due to heat, humidity, and pressure changes in the Nitrox flow and should only be used for rough estimates of %O 2. The Fill O 2 Analyzer supplies more accurate readings, within +/- 1% O 2. For Scuba cylinder fills, the user must always verify the fill with a third independent O 2 analyzer. Do not use this system to produce Nitrox mixtures containing more than 40% oxygen. Pumping Nitrox mixtures with higher concentrations of oxygen may lead to fires or explosions, which can cause serious personal injury or death. Do not pump Nitrox mixtures at pressures above the HP Compressor rating, and never above 3600 P.S.I. (250 bar). The system is not rated for pressures above 3600 P.S.I. (250 bar). Higher pressures may lead to explosions which may cause serious personal injury or death. No oxygen cleaning of standard cylinders or plumbing is mandatory when using the Nitrox System to produce Nitrox containing a maximum of 40% oxygen. When filling oxygen clean cylinders, hyper-purification of the Nitrox is required using an optional Oxygen Compatible Air purification system available from Nuvair. This Nitrox System does not produce Nitrox mixtures acceptable for 100% oxygen service. Never fill a cylinder that is marked, For Oxygen Service, with Nitrox that has been produced by anything other than 100% oxygen clean system. Filling an oxygen clean cylinder with breathing gas containing hydrocarbons can lead to explosions if the cylinder is subsequently filled with gas mixtures containing gas mixtures containing greater than 40% oxygen. Only provide Scuba cylinder Nitrox fills to customers who have proof of Nitrox training and certification. Improper use of Nitrox can be fatal. Page 24

25 This system is not cleaned for oxygen service and not all components are compatible with gas mixtures containing greater than 40% oxygen. Pumping gas mixtures containing greater than 40% oxygen will lead to explosions which may cause severe personal injury or death. Each Scuba cylinder belonging to a customer must be analyzed by that customer at the Nitrox filling facility, using an oxygen analyzer independent of those used with the Nitrox System. An employee must witness that the customer has properly analyzed the gas in each cylinder, noted the maximum operating depth for that mixture, and signed and dated the fill log. The time of day must also be included with the date, since some customers may fill the same cylinder more than once a day Pumping Nitrox 1) When filling a Scuba cylinder, follow all industry standards. Do not exceed rated pressure of cylinder, and do not exceed 3600 P.S.I. (250 bar) under any condition. 2) With fill whip bleed valve open and Nitrox flowing, verify that Fill Oxygen Analyzer %O 2 reading equals the desired Nitrox %O 2. 3) Close bleed valve, open cylinder valve, and fill cylinder. Monitor system for proper operation: a) Monitor Oxygen Analyzers and recalibrate as required b) Listen for proper operation of automatic condensate drains every minutes. c) Monitor all system gauges as shown in the table below. The Oxygen Analyzers may require re-calibration after minutes of operation due to humidity and temperature change effects on the Sensor. To recalibrate, turn off the LP Feed Air Switch and follow calibration instructions. When the HP Compressor auto drain engages and dumps condensate, the Fill Oxygen Analyzer reading will decrease momentarily due to the pressure drop in the system.

26 15.1 Pumping Nitrox (continued) 4) After filling is complete, close cylinder valve, vent the bleed valve, and remove the cylinder. 5) Test the Nitrox %O 2 in the cylinder using an independent Oxygen Analyzer such as the Nuvair O 2 Quickstick TM. Calibrate analyzer before use in accordance with manufacturer s instructions. 6) Repeat steps 1-5 until you have filled all Scuba cylinders. 7) Mark each tank with fill date, %O 2, fill pressure, and MOD (Maximum Operating Depth). 8) Log every Nitrox fill to document the following information: Fill date and time of day Tank Number Supplier s check of oxygen content (%O 2 ) plus signature and date User s check of oxygen content (%O 2 ) plus signature and date Fill Pressure MOD (Maximum Operating Depth) in user s handwriting Nitrox certifying agency and card number 9) When filling a HP Nitrox storage tank, verify that Fill Oxygen Analyzer %O 2 reading equals the desired Nitrox %O 2. Open applicable line valves and tank valve, and fill with Nitrox. Do not exceed rated pressure of cylinder, and do not exceed 3600 P.S.I. (250 bar) under any condition. After filling is complete, close all valves and allow Nitrox System to shut down Pumping Air To use the System to pump air, simply turn off the LP Compressor. No Nitrox will be supplied to the HP Compressor, and it will pump air only. When the HP Compressor is pumping air, the Permeate Oxygen Analyzer and the Fill Oxygen Analyzer should both read 20.9% O 2. Use Independent Oxygen Analyzer for Verification On/Off Switches On/Off Knob for HP Compressor LP Compressor Control Always use Oxygen Analyzers to monitor oxygen content of any gas flowing through the System. Both air and Nitrox are subject to variations in oxygen content Shutting Down 1) When the Storage Banks are finished filling and tank valves are closed, the Nitrox System will automatically shut down at the pressure set on the pressure switch (3600 psi). 2) Manually shut off the Membrane System by turning the Feed Air Regulator adjustment knob CCW to reduce pressure to minimum setting and then turn off the LP & HP compressors. 3) The system will automatically drain all Filter, Compressor, and Volume Tank condensate. Page 26

27 16.0 Nitrox Operation Notes 16.1 Correlation of Feed air Pressure to Oxygen Content After the 10 hour break-in period for your Nitrox System, you will notice that specific Nitrox %O 2 s always match specific feed air pressures once the System has warmed up. These pressures will be repeatable. If you find that the Fill Oxygen Analyzer reads 36% O 2 when the feed air pressure is at 125 P.S.I. (9 bar), record this pressure or make a mark on the feed air pressure gauge indicating the %O 2. Do this for each %O 2 that you normally make, making sure System has warmed up first. The next time Nitrox with 36% O 2 is needed, adjust the regulator to 125 P.S.I. (9 bar) and wait for the Oxygen Analyzer reading to stabilize. You will find the analyzer reading to be very close to 36% O 2, requiring only minor adjustments of the regulator to achieve the exact desired %O 2. Use the Fill Oxygen Analyzer to verify the Nitrox oxygen percentage prior to pumping. When using the feed air pressure reading to obtain specific oxygen percentage, minor adjustments of the feed air pressure regulator may be required to obtain the exact percentage desired Hot Fills While in the process of filling HP Nitrox Storage Tanks, you may have a need to supply a walk-in customer with a Scuba Cylinder fill of a different Nitrox mix. You can change mixes as follows: 1) With the Nitrox System operating, isolate the HP Nitrox Storage Tanks from the HP Compressor by closing the appropriate valves. 2) Record the Membrane System feed air pressure reading. 3) Slightly open fill whip valve on the HP Compressor, and adjust so the running Compressor maintains P.S.I. ( bar) outlet pressure. 4) Adjust the B.P. feed air regulator to the pressure corresponding to the desired Nitrox %O 2 for the Scuba Cylinder fill. 5) Allow the Fill Oxygen Analyzer reading to stabilize, make any minor adjustments necessary to achieve the desired %O 2, and then fill cylinder in normal manner. 6) When finished return regulator to previous setting, and allow the Fill Oxygen Analyzer reading to stabilize. Make any minor adjustments necessary to achieve the desired %O 2, and then resume filling Storage Tanks. Page 27

28 17.0 Maintenance The following list of daily and routine maintenance items is intended as a guide. Refer to LP and HP Compressor manuals for complete maintenance requirements Daily Maintenance Be sure to check Compressor Lubricant levels prior to each day of operation. Failure to ensure the proper lubricant level will lead to system damage. 1) Check lubricant levels of both LP and HP Compressors and add proper lubricants as required. See Section 17.3 and Compressor manuals for details. 2) Slightly open each HP and LP Manual Condensate Drain Valve to verify that no condensate is present. 3) Check LP Air Filtration for condensate and proper operation of condensate drains. Condensate Tank Filter Pressure Drain Use only the specified Nuvair Lubricants in this system. The use of incompatible lubricants presents a risk of fire and/or explosion, and may result in system damage. This can lead to severe personal injury and death. Be sure that all pressure has been relieved from the system prior to opening any filtration canister. Failure to vent pressure from the system prior to opening the canister can lead to serious personal injury or death. If system is located in an area where there is high humidity and high heat, the life of all Filtration Elements may be as little as 35% of rated operating capacity. Check the Compressor manual and Appendix for details on Filter Element Life Factors. Page 28

29 15.1 Routine Maintenance 1) LP Compressor Lubricant: Change Compressor Lubricant every 1000 hours or annually. Only use lubricants rated for use with Nitrox, such as Nuvair 546 TM. Never mix Compressor Lubricants. See Section 17.3 and LP Compressor manual for details. 2) HP Compressor Lubricant: Change Compressor Lubricant every 100 hours or annually, whichever comes first. Only use lubricants rated for use with Nitrox, such as Nuvair 455 TM. Never mix Compressor Lubricants. See Section 17.4 and HP Compressor manual for details. 3) LP Air Filtration Inspection: On a weekly basis, inspect each Filter Bowl for the presence of moisture and each Element for any unusual degradation or wetness. See Section 17.5 for details. Evidence of any moisture in the HF1-20 filter indicates air is not cooling properly. 4) LP Air Filtration Elements: Change LP Filter Elements every 500 hours or annually to maintain CGA Grade D air standards. Visual liquid level and service life indicators assist with monitoring replacement intervals. See Section 17.5 for details. If the Nitrox System is operated in high humidity and/or high temperature, Filter Elements must be changed more often. See Appendix for details on Filter Element Life Factors. 5) HP Compressor Filtration Element: Change HP Filter Element every 60,000 cubic feet of air or Nitrox processing to maintain CGA Grade E air standards. See Section 17.6 for details. If the Nitrox System is operated in high humidity and/or high temperature the Filter Element must be changed more often. See Appendix for details on Filter Element Life Factors. 6) Condensate Drain Container: Check level and drain weekly or as needed. 7) Semi-Permeable Membrane: No maintenance required. Service life exceeds 20 years if LP Air Filtration is properly serviced to maintain Grade D standards. 8) Membrane System Air Intake Filter: Inspect filter element every 3 months for visible particles. Change every 12 months or sooner if particles are visible. 9) Oxygen Analyzers: Replace Oxygen Sensor and Battery as required. See manual included with Nitrox System. Condensate Drain Container. Check & Drain Weekly. 10) Air/Nitrox Quality Analysis: Take breathing air/nitrox samples quarterly for analysis to assure compliance with CGA Grade E breathing air standards. Do not swallow (ingest) either the electrolyte from the Oxygen Sensor or the Sensor itself. The Potassium Hydroxide chemical contained in the Sensor can cause severe injury or death. If electrolyte or the Sensor is swallowed, seek medical attention immediately. If after handling the Oxygen Analyzer or Sensor, you find that your fingers or other parts of your body feel slippery or the skin or eyes sting, immediately flush affected area with clean, fresh water for at least 15 minutes. The stinging or slippery sensation is an indication of a leaking Sensor. The Potassium Hydroxide chemical contained in the Sensor can cause severe injury or death. Seek immediate medical attention if eye contact is made or skin stinging persists. Page 29

30 Use only the specified Nuvair Lubricants in this system. The use of incompatible lubricants presents a risk of fire and/or explosion, and may result in system damage. This can lead to severe personal injury and death Compressor Lubricant ( see page for material spec sheets) The LP Compressor in your Nitrox System comes standard with Nuvair 546 TM Synthetic Food Grade Compressor Lubricant for Rotary Screw Compressors. The HP Compressor comes with the Nuvair 455 Synthetic Food Grade Lubricant. Check lubricant levels at each Sight Gauge and add lubricant as required through the appropriate Fill Plug. Lubricant is removed through the Drain Plugs. See LP and HP Compressor manuals for details on servicing Lubricant Never mix lubricants! Rotary and Reciprocating oil are different! Do not carry out these tasks if the compressor has only just shut down; wait for the compressor to cool. Pressure must be drained before opening LP Fill Plug. Any oil spilt during the oil/filter change could cause personnel to slip; wear protective garments and anti-slip footwear and remove traces of oil immediately. Both oil and filter are classified as special wastes and must therefore be disposed of in compliance with the anti-pollution laws in force. All maintenance work must be carried out with the compressor OFF and the power supply lead unplugged from the main socket. Lubricant Fill Plugs Page 30

31 17.4 LP Feed Air Filtration Special attention needs to be given to the arrangement of the four LP Feed Air Filtration Elements and Bowls. Properly reinstall each Element and Bowl to the correct Housing. Improper sequence can cause damage to downstream components The use of Grade D or better feed air is critical to prevent the passing of any residual oil vapor into the Membrane System. Four stages of Hankison LP filtration are used to produce Grade D air: 1) Coalescing Filter 2) Coalescing & Water/Oil Vapor Removal to 1 Particulate micron 3) Coalescing & Water/Oil Vapor Removal to 0.01 Particulate micron 4) Final Stage - Oil Vapor Removal to PPM LP Filtration Inspection Open each Filter and inspect as follows: 1) Inspect Bowl for the presence of moisture. A high level of moisture build-up in the HF11-20 or HF7-20 Filter indicates improper operation of auto-drain floats. Evidence of any moisture in the HF1=20 Filter indicates air is not cooling properly and moisture is not properly being removed. Excess moisture will prevent the final filter from operating properly and can lead to damage of the membrane. Air Flow Housing Air Flow HF1-20 HF5-20 HF7-20 HF11-20 Oil Coalescing Particle Vapor &Water/Oil & Coalescing Removal Vapor Moisture Removal Removal Replacement Element Part Number E1-20 E5-20 E7-20 E11-20 Bowl Element HF11-20 Filter with Auto-Drain Float & Liquid Level Indicator HF1-20 Filter with Manual Drain Should not Contain Moisture HF5-20Filters with Auto- Drain Float & Liquid Level/ Service Indicators HF7-20 Filter with Auto- Drain Float & Liquid Level Indicator Page 31

32 Changing LP Filtration Elements Change Filter Elements every 500 hours or annually. If the Nitrox System is operated in high humidity and/or high temperature, Filter Elements must be changed more often. See Appendix for details on Filter Element Life Factors. Visual service indicators on the HF5 & HF7 filters assist with monitoring replacement intervals. 1) Push up on Filter Bowl, rotate counter-clockwise, and lower to remove. 2) Gently unscrew Filter Element and pull down off mounting post. 3) Replace Element and reassemble in reverse order. Changing LP Filtration Element The interior of the Filter Bowls can be cleaned with a diluted solution of Simple Green TM and flushed thoroughly with clean water. This will assist to prolong the life of the element, bowl, and auto drain. Page 32

33 17.5 HP Compressor Filtration The HP Compressor comes standard with Triplex filtration, utilizing a single Filter Element. Do NOT use any substitute. Change Filter Element every 60,000 cubic feet of air or Nitrox processing. If the Nitrox System is operated in high humidity and/or high temperature, Filter Element must be changed more often. See Appendix for details on Filter Element Life Factors. 1) Shut down the Nitrox System 2) Open Manual Bleed Drain Valve to drain pressure. Leave Valve open. 3) Unscrew the Filter Canister Cap. 4) Remove expended Element from Filter Canister. 5) Install New Element place pressure on element to seat the element. 6) Reinstall Cap to Canister. 7) Close Manual Condensate Valves.

40 OWNER S WARRANTY RESPONSIBILITIES Voyager III TM Nitrox System Failure of the owner to prevent equipment damage by complying with the procedures outlined below and in the Operation Manual will void the Nitrox System warranty. Installation: All set up requirements and procedures provided in the Nitrox System Operation Manual must be followed in their entirety including supply air cleanliness, Compressor preparation, and installation of the Nitrox System. Supply air to the Membrane must be properly filtered to CGA Grade D air quality or better to prevent damage to the Membrane. Air quality testing of the supply air should be performed periodically and documented to assure compliance. If there is any doubt regarding the suitability of a HP or LP Compressor for compressing Nitrox, contact Nuvair or the Compressor manufacturer before you connect your Nitrox System. If an existing HP or LP Compressor is to be used for compressing Nitrox, all traces of the old lubricant must be removed and replaced with a Nitrox Compressor Lubricant approved by Nuvair. Electrical wiring and connections should be made by a qualified electrician in accordance with all national and local electrical codes. Do not change the temperature setting on the Heater Thermostat Control. Changes in temperature settings may cause Membrane damage. To prevent Compressor damage, only use the Compressor Intake Hose provided. If a longer hose is required, contact Nuvair for assistance. Compressors must be provided adequate ventilation to operate properly and prevent heat damage. This requires an ambient temperature below 100 o F (38 o C), sufficient clearance from adjacent walls, and proper rotation direction. Operation: Do not use the Nitrox System to supply a HP or LP Compressor with Nitrox mixtures containing more than 40% oxygen. Compressing higher concentrations of oxygen may cause severe Compressor damage. Do not pump Nitrox mixtures at pressures above the Compressor manufacturer s rating, and never above 3600 P.S.I. (250 bar). Compressing Nitrox at higher pressures may cause severe HP Compressor damage. To prevent Membrane damage, drain all low pressure filter and volume tank condensate on a daily basis. If you become aware of an operational fault, stop using the equipment immediately and contact Nuvair for assistance. Maintenance: Change low pressure filter elements on a schedule determined by filter capacity and ambient temperature and humidity. Contact Nuvair if you need assistance establishing a schedule for your equipment and location. Replace Membrane System Air Intake Filter on a regular basis to prevent flow obstruction. Keep all nuts, bolts, fittings, connectors, and clamps tight. Keep a service record book showing that regular maintenance work has been carried out.
